FastPath Handlers

Currently RouterOS has following fast path handlers:

  • ipv4
  • traffic generator
  • mpls
  • bridge
Icon-note.png

Note: Packet will be forwarded in fast path only if source and destination interfaces support fast path. See the list of supported interfaces.



IPv4 handler

IPv4 fast path is automatically used if following conditions are met:

/ip firewall connection tracking set enabled parameter has new auto value Which means that connection tracking is disabled by default until firewall rules are added.


Traffic Generator handler

Traffic Generator fast path is automatically used for interfaces that support this feature.


MPLS handler

MPLS fast path is automatically used for interfaces that support this feature.


Bridge handler

Bridge fast path is automatically used if following conditions are met:
